Solar-Powered Bluetooth Speaker
Portable Back-up Battery
Eton BoostTurbine
The Eton BoostTurbine back-up battery charges most mobile devices via a USB port. Its special feature is, however, hidden on its reverse side. There you will find a hand-operated winding mechanism, which can be turned to produce energy without using mains electricity. The energy thus produced is sufficient to power a mobile phone long enough to make a short phone call, making BoostTurbine a useful device in an emergency. The battery is made using aluminium die casting, polycarbonate and rubber and stands out thanks to its perfect size.
评审团评语
This elegant back-up battery won us over because it makes it possible to produce electricity mechanically at any time and is so giving the user an increased level of independence.
